Bronchoscopy clinical trials

Investigating the Role of ATP Production by Airway Epithelium in Patients With Refractory and Unexplained Chronic Cough (RCC/UCC).

This study looks into why some people have a chronic cough that doesn't go away. Researchers are checking tiny cells in the airways to see if a chemical called ATP is linked to this cough, hoping to find better ways to treat it.
